Why men's and women's clothes have buttons and zippers on different sides

Many garments fasten differently for men and women, including buttons and zippers. A common explanation comes from European fashion history, when wealthy noblewomen wore complex dresses that required assistance to dress. Buttons were often positioned to make it easier for a servant to fasten the clothing while facing the wearer. Since about 90% of people are right-handed, the placement could align with the servant’s dominant hand. Over time, these practical choices became design traditions. As clothing manufacturing continued, the conventions stayed linked to gender, so small details like zipper direction can reflect earlier social and production patterns.

Examining the material culture of the past can reveal how people lived, worked, and thought in earlier times. Fasteners like buttons and zippers aren't just practical. They also follow design traditions that became connected to gender over hundreds of years."

"One of the most common explanations for why male and female garments have their buttons on opposite sides comes from European fashion history. A long time ago, wealthy women from the nobility often wore complicated dresses with buttons and fasteners-so complicated that they needed help getting dressed. Some historians believe buttons were placed in a way that made it easier for a servant to fasten the clothing, reflecting class distinctions."
